An electronic component such as a hard disk is accommodated in the case 10. The cover 30 is attached to the back side of the case 10 and the display unit 2. In other words, the cover 30 is attached to the main body side of the electronic device A.

  As shown in FIG. 1B, the cover 30 covers the connector group CG provided on the back side of the display unit 2. A sheet metal 20 and a holder H are fixed to the case 10. The holder H is for bundling cables connected to any connector of the connector group CG. The cover 30 is formed with a notch 32c for releasing a cable connected to any connector of the connector group CG. The case 10 and the cover 30 are provided with a plurality of claws 19 and 39 that engage with each other. The cover 30 is provided with insertion ports 31a, 32a, 32b and a slider 40. The insertion ports 31a, 32a, and 32b are examples of the first opening, the second opening, and the third opening, respectively. The slider 40 is an example of an operation unit.

  2A and 2B are enlarged views of the periphery of the cover 30. FIG. The cover 30 includes an upper wall 31, a back wall 32, and a side wall 33 that are substantially orthogonal to each other. The insertion port 31 a and the exposure hole 31 b are formed in the upper wall 31. The upper wall 31 is an example of a first wall portion. The insertion ports 32 a and 32 b are formed in the back wall 32. The back wall 32 is an example of a second wall portion. As will be described later, the insertion ports 31a and 32a are inserted with cables to prevent theft. A lock device for preventing theft is inserted into the insertion port 32b. The lock device is a key-like device that can be inserted into a so-called security slot, such as a Kensington lock device, but is not limited thereto. A knob 41b formed on the slider 40 is exposed from the exposure hole 31b. As will be described in detail later, the cover 30 shifts to a locked state in which the cover 30 is locked to the case 10 or an unlocked state in which the lock is released in accordance with the sliding operation of the slider 40. In the locked state, removal of the cover 30 from the case 10 is restricted. In the locked state, the insertion ports 31a, 32a, 32b are opened, and in the unlocked state, the insertion ports 31a, 32a, 32b are closed. FIG. 2A shows the unlocked state, and FIG. 2B shows the locked state.

  FIG. 3 is a view when the wire W is inserted into the insertion ports 31a and 32a in the locked state. The wire W is an example of a member to be inserted. Although described in detail later, the transition from the locked state to the unlocked state is restricted by the insertion of the wire W. Thereby, the removal of the cover 30 from the case 10 is regulated. A third party is restricted from accessing the connector group CG without permission. When the insertion ports 31a, 32a, and 32b are opened in the locked state, the wire W can be inserted into the insertion ports 31a and 32a, and the lock device can be inserted into the insertion port 32b. For example, the wire W is provided with a lock that connects one end and the other end at one end. The wire W cannot be removed from the cover 30 by inserting the wire W into the insertion ports 31a and 32a and then closing the lock with the lock opened. The transition from the locked state to the unlocked state is also restricted by inserting a lock device into the insertion port 32b and performing a predetermined operation on the Kensington lock device.

  Since the insertion ports 31a and 32a are closed in the unlocked state, the insertion of the wire W is prevented. For example, if the insertion ports 31a and 32a are opened and a wire can be inserted even in the unlocked state, the following problem may occur. The user may misunderstand that the security of the electronic device is ensured by inserting the wire W into the insertion ports 31a and 32a in the unlocked state. In the present embodiment, since the insertion ports 31a and 32a are closed in the unlocked state, the insertion of the wire W is prevented. Therefore, the security of the electronic device A is improved. Further, the user can easily grasp immediately whether or not one of the insertion ports 31a and 32a is closed by checking whether or not one of the insertion ports 31a and 32a is closed. Further, since the insertion ports 31a and 32a are separately formed on the non-parallel upper wall 31 and the back wall 32, the user can easily see at least one of the insertion ports 31a and 32a.

  For example, when a metal plate in which a hole for passing a cable is formed protrudes outward from the wall of the cover 30, such a plate may interfere with cable connection work or the like. In this embodiment, since the insertion ports 31a and 32a are formed in the upper wall 31 and the back wall 32, respectively, there is no possibility that the work will be disturbed. It also has an aesthetic appearance.

  Moreover, it is suppressed that a foreign material penetrate | invades in the cover 30 via insertion port 31a, 32a, 32b. Further, when the lock is not used, the insertion ports 31a and 32a can be closed, so that the aesthetic appearance is excellent.

In addition, the support wall 61 and the presser wall 62 are formed with guide portions 65 that are inclined with respect to the support wall 61 and the presser wall 62. The guide portion 65 surrounds the insertion ports 31a and 32a of the cover 30 so that they can communicate with each other. The slider 40 and the sheet metal 50 are slidably held between the cover 30 and the sheet metal 50.

  FIG. 9A is a cross-sectional view of the periphery of the cover 30 in the locked state. FIG. 9B is an enlarged view of FIG. 9A showing the engaged state with the claws 19 and 39. The claw 19 is formed by processing a part of a thin metal plate formed along the side wall of the case 10. By inserting the claw 39 between the claw 19 and the side wall of the case 10, the cover 30 is fixed to the case 10.

  Next, the locked state and the unlocked state will be described. FIG. 10A is an explanatory diagram of a locked state, and FIG. 10B is an explanatory diagram of an unlocked state. As shown in FIG. 10A, the movable wall 53 of the sheet metal 50 is retracted from the fixed wall 23 by sliding the slider 40 to the back wall 32 side of the cover 30 from the state in which the pin 53p is inserted into the hole 23a. The pin 53p slides out of the hole 23a. Thereby, the cover 30 can be removed from the case 10. In addition, the slider 40 closes the insertion port 31a from the state retracted to the insertion port 31a. As shown in FIGS. 10A and 10B, a seal 49 as an index indicating an unlocked state is attached to one side of the two portions of the slider 40 separated by the knob 41b. In the unlocked state, the seal 49 is exposed from the exposure hole 31b. Such a seal 49 may not be provided.

  FIG. 11A is a cross-sectional view of the cover 30 in the locked state, and FIG. 11B is a cross-sectional view of the cover 30 in the unlocked state. When the wire W is inserted into the insertion ports 31 a and 32 a in the locked state, the wire W passes through the escape holes 51 a and 52 a of the sheet metal 50. Thereby, even if the slider 40 is operated, the wire W regulates the sliding of the sheet metal 50 and the slider 40. This restricts unlocking. Even when the locking device is inserted into the insertion port 32b, the locking device restricts the sliding of the sheet metal 50.

  The holder 60 partitions the space in the cover 30 facing the insertion ports 31a and 32a from the other spaces while ensuring the communication between the insertion ports 31a and 32a. This state is the same in both the locked state and the unlocked state. For this reason, it is suppressed that a foreign material penetrate | invades in the cover 30 via insertion port 31a, 32a. Further, in a state where the insertion openings 31a and 32a are opened, the guide portion 65 of the holder 60 inserts the wire W into one of the insertion openings 31a and 32a and guides it so as to pass the other. Thereby, attachment of the wire W becomes easy.

  A protruding convex portion 66 is formed on the surface of the support wall 61 of the holder 60 that faces the upper wall 31 of the cover 30. A recess 46 is formed on the lower surface of the slider 40 facing the support wall 61 of the holder 60. In the locked state, the knob 41b of the slider 40 is engaged with the convex portion 66, and one end of the slide range of the slider 40 is defined. In the unlocked state, the concave portion 46 of the slider 40 engages with the convex portion 66 to define the other end of the slide range of the slider 40.

  Further, as described above, the slider 40 and the sheet metal 50 that closes or opens the insertion ports 31a, 32a, and 32b are formed separately. For this reason, for example, the slider 40 and the insertion ports 31a, 32a, and 32b can be provided at different positions by changing the shape of the sheet metal 50 and the shape and size of the slide groove 51s. Thereby, the freedom degree of the position which provides the slider 40, and the position of insertion port 31a, 32a, 32b improves.

  The sheet metal 50 is provided at the corner of the cover 30 in which the insertion ports 31a and 32a are formed. For this reason, the sheet metal 50 can reinforce the periphery of the insertion ports 31 a and 32 a of the cover 30.

  In the above-described embodiment, the pin 53p is provided in the metal plate 50, and the hole 23a through which the pin 53p passes is provided on the metal plate 20 side, but the present invention is not limited to this. For example, a hole may be provided in the movable wall 53 of the sheet metal 50 and a pin that can penetrate the hole may be provided on the sheet metal 20 side.

  In the above embodiment, the escape hole 51a of the sheet metal 50 is retracted to the insertion port 31a, whereby the insertion port 31a is closed by the horizontal plate 51 and the insertion port 31a is also closed by the slider 40. Therefore, the sheet metal 50 may not be provided with the horizontal plate 51. Moreover, the slider 40 does not need to close the insertion port 31a. Further, the sheet metal 50 opens and closes the two insertion ports 31a and 32a, but only one of them may be closed and opened, and the other may always be opened.

  Next, the slider 40a and the sheet metal 50a which are modifications will be described.
